FREDERICK W. COLE, OF NEWTON, MASSACHUSETTS, ASSIGNGR TO THE GAME'WELLFIRE ALARM TELEGRAPH COMPANY, G1 NEW' YORK, N. 2., A CORPORATION OF NEWYORK.

SUPERVISORY SIGNALING DEVECE FGR CLOCKS.

To all whom it may concern:

Be it known that I, FREDERICK V. COLE, of Newton, in the county ofMiddlesex and State of Massachusetts, have invented an Improvement inSupervisory Signaling Devices for Clocks, of which the following is aspecification.

This invention relates to supervisory signaling-devices for clocks orother timingmechanisms, and has for its object to provide asignaling-device adapted to be operated to cause a notification signalto be given or transmitted to a central-station, especially in case theclock or other timingniechanism becomes disabled. It is of especialvalue in connection with automatic fire-alarm and watchmans supervisorysignal-systems in which the continual operation of timing-devices isdepended upon for sending signals or causing signals to be sent, andalso for recording the signals. The invention is also applicable toother systems and apparatus embodying a timing-mechanism, when it isdesired that notification shall be given when said mechanism becomesdisabled or runs too fast or too slow.

The invention consists in embodying a timed-supervisorymechanism inconnection with the timing-mechanism, and a signal ingdevice forindicating the stopping; of the timing-mechanism, or of either thetiming-mechanism or the timed-supervisorymechanism, and also forindicating when the timing-mechanism and timed-supervisory-mechanism arerunning out of synchronism., so that in case of any trouble whereby thetiming-mechanism is disabled or its control affected, notification willbe. given.

A signaling-device is preferably employed and its circuit is adapted tobe operated or controlled by the joint action of said timing-mechanismand timed-supervisory-mechanism, so that it may be oper ated by either,in case one ceases to operate, or in case they run out of synchronism.The signaling-device employed will prefer ably be a code-signaltransmitter, and in such case several may be connected in a singlecircuit connected with a central-station, and when more than onetransmitter is employed different identification signals will be sent.The code-signal transmitter is aplapted to be released or otherwiseoperatec.

Figure 1 is a. front view of a suflicient portion of a watchmans clockto illustrate this invention, together with means embodyingthisinvention for operating a sig- 112ill11'*(lQVlCG in case said clockstops or runs too fast or too slow. Figs. 2 and 3 are details to bereferred to. Fig. 4 is a side view of the parts shown in Fig. 1. Figs.5, 6 and 7 are details to be referred to. Fig. 8 is a diagram of thecircuit to be referred to. Fig. 9 is an enlarged detail of one of thecontact-members, together with a diagram of a circuit having a modifiedform of signalingdevice, and, Figs. 10 to 15 inclusive are detailsshowing modified forms of circuit-opcrating devices for the circuit ofthe signaling-device.

(4 represents the removable dial of any usual or suitable watchmansclock, or equivalent timing-mechanism, and a" one of severalelectro-magnetically operated markers for marking or puncturing .thedial or otherwise indicating a signal thereon in re sponse to theoperation of a circuit, such as n, Fig. 8, by a watchman.

(4 represents a toothed wheel which may be secured to the minute-shaftofthe timing-mechanism, which is engaged by an idle pinion (4 which inturn engages a toothed wheel a, secured to a shaft 0", so that saidtoothed wheel a revolves in synchronism with the toothed wheel a makinga complete revolution once an hour. A hand a is secured to the shaft awhich moves over a small dial c lVith the exception of moving the minutehand a to one side of the center of the clock-train and mounting it onan independent shaft instead of connecting it with the shaft bearing thetoothed wheel (4 the timing-mechanism thus shown is constructed as theordinary watchmans clock, but is here shown particularly forillustration. Hence my invention is not limited to any particularconstruction of timing-mechanism, or to the employment of a dial andcooperating devices whereby it is adapted to serve as a. watchmansclock.

Z) represents one of the train-wheels of a timed-supervisory-mechanismof any usual or suitable construction. and l) the minuteshaftthereof. Apendulum clock is here shown as the timed-supervisory-mechanisin, merelyfor the purpose of illustration. Said timed-supervisory-mechanism istimed to run in synchronism with the aforesaid timing-mechanism, and, ashere shown, is designed to be employed as a controller for saidtiming1nechanism, and also to be controlled by said timing-mechanism. Incarrying out. this part of my invention, as shown in Figs. 1 to 9, theminute-shaft a of the timing-mechanism and the minuteshaft 6 of thetimedsupervisory-mechanism, each having secured to them a disk, and saiddisks, represented at c and 6!, respectively, are arranged eccentricallyon their shafts and in the same relative positions. The eccentric disk 0is embraced by the forked end of a lever c, pivoted at a and having anupwardly extended arm 0 provided with a bifurcated laterally extendedfinger 0*, which embraces an ear 0', arranged at the lower end of andprojecting at right angles from an upright shaft. 0", supported bysuitable end bearings, so that as the minute-shaft c revolves, saidlever moves back and forth slowly on its pivot, making one completevibration during each complete revolution of the minute-shaft, and theshaft a correspondingly reciprocates rotarily, moving through a shortare. The eccentric disk (Z is embraced by the forked end of a lever cl,pivoted at (F, and having a downwardly extended arm (Z composed ofinsulating material, which bears a pair of contact-pens (Z (Z the endsof which are extended below the end of the arm and are spaced apart. Asthe shaft 6 revolves the lever (Z moves back and forth slowly on itspivot, making one complete vibration during each complete revolution ofthe disk and the arm (Z bearing the contact-pens correspondinglyvibrates. The upper end of the reciprocating shaft 0 bears a short arm 0see Figs. 5, G and 7, which projects therefrom at right angles, andbears a contactpen 0 which projects into the space between the twocontact-pens (Z (Z and normally occupies a middle position therebetween.

Assuming the timing-mechanism and timed-supervisory-mechanism to be setat unison, and the contact-pen c disposed midway between thecontact-pens d, (Z it will be seen that as long as they run insynchronism, the levers will be moved by the eccen tric disks and therelative positions of the contact-pens d, (Z and 0 will remainunchanged, see Fig. 5, and the circuit m of the signaling-device willnot be operated, but in case the timing-mechanism stops the contact-pen0 will cease to move and will be soon overtaken by one of thecontact-pens (Z or (Z and engagement effected, see Fig. 6, whereby thecircuit in see Figs. 8 and 9, including said cont, ct-pens will beoperated, and in case the timed-supervisory-mechanism stops thecontact-pens (P, (Z will cease to move and one of them will be soonovertaken by the contact-pen 0 and said circuit m operated. Or, in caseeither the timingmechanism or timedsupervisory-1nechanism runs out ofsynchronism with the other, as for instance, too slow or too fast, thecontact-pen will be moved relatively to each other and into engagementto operate said circuit in. Thus the signaling-device is prevented fromoperation by the timing-mechanism and timed-supervisory-mechanism,acting conjointly, when running in synchronism, but is permitted orcaused to operate whenever either stops or when they run out ofsynchronism, the means to operate said signaling-device being automatic.

The circuit 127., includes a battery m, and may include areleasing-magnet m, see Fig. 8, for a code-signal-transmitting-device mwhereby a code-signal, for instance an identification-number, will besent over a circuit m, which will operate the recorder m, or othersignaling-device. In lieu of employing a recorder as a signaling-device,the circuit m may directly include a bell. m, or other form of alarmapparatus, see Fig. 9. Thus, in case either the timing-mechanism ortimed-supervisory-mechanism stops, or runs out of synchronism with theother, the sigiulling-device is operated to give notification of thetrouble. '7

In lieu of the means above described for operating the signal-circuit,the form shown in Fig. 10 may be employed, wherein the aforesaideccentric disks 0 and (Z are re spectively arranged to directly operatepivoted levers e and 6, bearing electric contacts for thesignal-circuit. Or the form shown in Fig. 11 may be employed wherein theeccentric disks 0 and (Z respectively operate spring-acting pivotedlevers c and c, bearing electric contacts for the signal-circuit. Or theform shown in F 152 may be employed wherein one of the contact-pens, asf, for the signal-circuit, is connected with "the minute-shaft of thetimed-supervisorymechanism, and its cooperating contact pen f isconnected to a sleeve f mounted on said shaft, and is operated by theminute-shaft of the timing-mechanism by belt or other suitable means,said contactpens being insulated from each other and arranged to engageeach other in case either the timingmechanism ortimed-supervisory-mechanism stops or runs out of synchronism with theother. Oathe form shown in Figs. 13 and 14, may be employed wherein oneof the con tact-pens, as g, for the signal-circuit is fixed and theother, as g, is movable, and said movable contact-pen engages a cam-disk9 arranged on a sleeve on a shaft g", and said disl-c bears a bevelpinion g, which is interposed between a pair of bevel-gears y, oneconnected with the minute-shaft of the timing-mochanism and the otherwith the minute-shaft of the timed-supervisorymechanism, so that in caseeither tl1eti1ning mechanism or timed-supervisory-mechanism stops orruns out of synchronism with the other, said bevel -pinion g will travelaround the bevel-gears, and the cam disk to which it is connected willbe rotated to lift the contact-pen g and operate the signalcircuit. Orthe form shown in Fig. 15 may be employed, wherein two circularlyarranged sets of contact-plates 7L and h, are provided, one for thetiming-mechanism and the other for the timed-supervisory-mechanism, overwhich move contact-pens or wipers 7L2, h which are connectedrespectively with the minute-shafts of said timingmechanism andtimed-supervisory-mechanism, and said contact-pens are connected in thesignal-circuit, as shown, so that said circuit may be operated by eitherwiper.

From the many modifications shown, it will be apparent that I do notdesire to limit my invention to the particular means here shown foroperating the signal-circuit, as long as said means is arranged andoperated by either the timing-mechanism or timedsupervisory-mechanism,in case the other stops or runs out of synchronism.
